My name is Terell Dunn. I'm majoring in mechanical engineering at the University of Alabama in Huntsville. I modelled a sequentially shifted, five speed manual transmission of my own design.
The transmission is of the synchro-less, constant mesh type. Dog clutches are used to engage each gear. I included the center differential within the transmission. All of the gears' teeth were designed with true involute curve geometry using the table driven curve command. For the spur gears, a helix was used to sweep the involute tooth profile along the gear axis. A loft was used to create the tapered tooth of the bevel gears. 63 unique parts were used in the model for a grand total of 337 parts.
